Plaque is the sticky, colorless film of bacteria that forms on
teeth. It makes teeth feel "fuzzy" to the tongue and is most
noticeable when teeth are not brushed.
What causes plaque and why is it harmful?
Plaque
develops when foods that contain carbohydrates (sugars and
starches), such as milk, soft drinks, raisins, cakes, or candy, are
frequently left on the teeth. Bacteria that live in the mouth
thrive on these foods and produce acids. Over a period of time,
these acids destroy tooth enamel, resulting in tooth decay. Plaque
can also develop on the tooth roots under the gum and cause
breakdown of the bone supporting the tooth.
How can plaque formation be prevented?
- Brush your teeth at least twice a day with a soft, rounded-tip
bristled toothbrush. Pay particular attention to the space where
the gums and teeth meet. Use a toothpaste that contains
fluoride.
- Floss between teeth at least once a day to remove food
particles and bacteria.
- See your dentist or oral hygienist every 6 months for a
check-up and teeth cleaning.
- Ask your dentist if a dental sealant is appropriate for you. A
dental sealants is a thin, plastic coating that is painted on the
chewing surfaces of teeth to protect them from cavities and
decay.
- Eat a balanced diet and limit the number of between-meal
snacks. If you need a snack, choose nutritious foods such as plain
yogurt, cheese, fruit, or raw vegetables. Vegetables, such as
celery, help remove food and help saliva neutralize plaque-causing
acids.
